The idea is
to complete series of 3 bubbles of the
same color touching each other by shooting upwards those
that appear in the base. Completed sets of 3 bubbles of the same
color will fall along with
any other bubbles attached at the bottom of the set.

Press
L or J to change
the angle of the shooter; Press K to shoot
The arrow keys work in some navigators

The first 3 falling bubbles get 1 point each, every additional falling
bubble gets 2 more points. If the match making bubble ever bounces
the table border, each bounce gets 5 more points.

The game Bubbles
has 10 levels , when completing each level a bonus of 100
points will be added to the score.

A base line is placed above the score board, when a bubble
touches that line the game is over.
